Ipomoea alba, known in English as white tropical morning glory, moonflower or moonvine, is a species of night-blooming morning glory,[3] native to tropical and subtropical regions of North and South America, from Argentina to northern Mexico, Arizona, Florida[4] and the West Indies.[5] Though formerly classified as genus Calonyction, species aculeatum, it is now properly assigned to genus Ipomoea, subgenus Quamoclit, section Calonyction.[6]

 

Description

Ipomoea alba is a perennial, herbaceous liana growing to a height of 5–30 m (20–100 ft) tall with twining stems. The leaves are entire or three-lobed, 5–15 cm (2–6 in) long, with a stem 5–20 cm (2–8 in) long. The flowers are fragrant, white or pink, and large, 8–14 cm (3–6 in) diameter. The flowers open quickly in the evening and last through the night, remaining open until touched by the morning dew. On overcast days, the blossoms may remain open for longer. The flowers also tend to remain open longer during cool temperatures, which may also cause the segments to snag or tear as they open
